I was puzzled by why TinyMCE in WordPress only shows one row of editing buttons. I checked the current post.php and it is showing ‘theme’ => ‘advanced’. Another possibility was that wp_tiny_mce function was calling the Teeny mode to be used. But that function has been deprecated.

I read people talking about Show/Hide Kitchen Sink button. It just sounded absurd. I couldn’t find it. Installed tinyMCE advanced plugin, still one row of button. After 1 more hour of googling, I ran into “how/Hide Kitchen Sink” again.  This time, there was a picture!! Ha.
